When launching FIFA 20 on my PS4, I have trouble signing in to the "EA SPORTS FOOTBALL CLUB" thing. I know my WiFi connection is fine. I can stream movies and series on Netflix without a problem.
I am sometimes able to sign in to EA on PS4, but in those rare cases, it is after several attempts. It has been like that for some time now. I know I have not been hacked or something because I am able to log in to my account on desktop, I have activated two-factor authorization, and I have changed my password after these problems occurred.

Please help me.
